Compendium sharing and buying new sourcebooks: buying and sharing a sourcebook as a player

Hi, all!  I have been playing DnD here on Roll20 for a while, and have been hearing great things about the new WoTC release "Tasha's Cauldron of Everything". I'm interested in getting it, but I worry that I'm not going to be able to access it neatly and especially not have an easy way to share it with my friends. For the first point, it seems like the only way to access the material there would be in-game? (And if you're on the basic subscription, you only get to designate one game for it?) To expand on the second point, it seems like unlike in DnD Beyond, only the owner of a game gets to share compendiums. Which is to say, I can't have individual members of my playgroup buying their own sourcebooks and pooling them. i.e. if I'm not the forever GM, as a player, it's not useful for anyone else. Does that seem about right, or is there something I'm missing?

You are correct on the sharing at the free level. You can make the content a little more accessible with this Stupid Trick . And yes, only the owner of the game can grant sharing within that game. The owner of a game can promote any player to GM status, at which point they would be running the game that has the shared material. D&DBeyond has a much closer connection with WotC, and has different rules they must operate under. For instance, they are more integrated with D&D than any other digital source, but at the same time, their Pathfinder content doesn't (and probably can never) exist. Roll20 isn't as polished or as expansive with their sharing policy, and probably never can be, both in terms of licensing agreements and amount of programming resources that can be devoted to the system. Whatever you choose as your digital source, there is give and take.

Okay, that's good to know. And thanks for sharing the "Stupid Trick"! That might make me give it a try!
